Will my current employer know I'm being sponsored for the 7&66

I'm currently series 6&63 license and a company is willing to sponsor me to take the series 7&66. Will my current employer know that this other company has open this window for me. I am seeking other employment opportunities and this company is not requring me to quite m y job until I pass the exam.

Well they want me to pay for my own exam.They stated that they will do a background check to open the window for me. I explained to them if I have to pay for my own exam than I can not quit my current job. They understood that. That is why I was told that it would be ok to continue to work at my current employer.
